## What it is
Open Brain is a self-hosted personal memory infrastructure combining a vector-search database, an AI gateway, and an MCP server so any AI tool (Claude, ChatGPT, Cursor) shares one persistent memory of the user. It is built on Supabase with a Slack capture channel and an open protocol plus community recipes and dashboards.

## Use cases
- give all my AI tools a shared persistent memory of me
- self-host a personal knowledge base with vector search
- connect Claude and ChatGPT to my own notes via MCP
- capture thoughts from Slack into a searchable brain
- replace SaaS note apps with an open memory layer
- migrate my memories between AI assistants

## When to choose
- you want one self-hosted memory store shared across multiple AI tools
- you're comfortable with a ~45-minute setup involving Supabase and MCP
- you want an open protocol instead of proprietary SaaS middleware

## When to avoid
- you just want a polished notes app with a GUI out of the box
- you don't want to manage your own database and cloud services
- you need a fully turnkey hosted solution with support guarantees
